I Ching Oracle
Cast six lines with the three-coin method. The primary hexagram, changing lines, and relating hexagram reveal the structure of your question.
The 64 Hexagrams
Your I Ching Reading
What your consultation reveals and how to read it
The I Ching, or Book of Changes, reads a situation through six lines built from the bottom upward. Each line is formed by a three-coin cast. Together the six lines create a hexagram. If changing lines appear, they transform the first hexagram into a second one, revealing how the situation may be moving, developing or changing.
How the consultation works
Begin with one clear question. The three coins are cast six times. Every throw creates one line, and the lines are placed from the bottom of the hexagram to the top.
When all six lines are complete, you receive your Primary Hexagram. This describes the main structure, condition and pattern surrounding your question at the time of the cast.
The three-coin method
Each coin has a value. Heads counts as 3 and Tails counts as 2. The values of all three coins are added together.
- 6 — changing Yin line
- 7 — stable Yang line
- 8 — stable Yin line
- 9 — changing Yang line
Yin and Yang lines
A solid line is Yang. It can indicate movement, initiative, outward force, action or a more active condition.
A broken line is Yin. It can indicate receptivity, openness, patience, support, inward movement or a condition that is developing through response rather than direct force.
Changing lines
A changing line is especially important because it shows a place where the situation is not remaining fixed. A value of 6 changes from Yin to Yang, while a value of 9 changes from Yang to Yin.
These changing lines create the Relating Hexagram. Read them as the movement between the present structure and what the situation is becoming.
The Primary Hexagram
The Primary Hexagram is the main answer to your question. It describes the current field: what is present, what is shaping the situation, where tension or support exists and what kind of response is most appropriate.
If there are no changing lines, this hexagram remains the central focus of the consultation.
The Relating Hexagram
When changing lines are present, the Relating Hexagram shows the direction of movement created by those changes. It can help you see what the situation is moving toward, what is emerging or what may become more important next.
Read the Primary and Relating Hexagrams together rather than treating them as two unrelated answers.
The Eight Trigrams
Every hexagram is built from two three-line trigrams. The lower trigram forms the bottom half and the upper trigram forms the top half. Their relationship adds another layer to the reading.
- Qian — Heaven: strength, initiative, creation
- Dui — Lake: openness, exchange, joy
- Li — Fire: clarity, awareness, attachment
- Zhen — Thunder: movement, awakening, sudden action
- Xun — Wind: gradual influence, penetration, growth
- Kan — Water: depth, risk, endurance
- Gen — Mountain: stillness, limits, stopping
- Kun — Earth: receptivity, support, nourishment
The Five Elements
The wheel also groups the trigrams through the Five Elements: Metal, Wood, Water, Fire and Earth. These help show the quality of the forces surrounding the hexagram.
Rather than reading one element alone, look at how it sits beside the trigram, the primary hexagram and any changing lines that appeared in your cast.
How to read the 64-hexagram wheel
The outer wheel contains all 64 hexagrams. After the cast, your Primary Hexagram becomes highlighted. If changing lines create a Relating Hexagram, that second hexagram is highlighted as well and the movement between them becomes visible.
The surrounding rings show Chinese names, elemental families, the complete hexagram field, the Five Elements and the Eight Trigrams. Use the zoom controls to inspect these layers more closely.
How to use your question
Ask about one situation at a time. Questions about direction, relationships, decisions, uncertainty, timing, change or a challenge work especially well when they are open enough to allow guidance.
After receiving the cast, return to your original question and notice which parts of the Primary Hexagram, changing lines and Relating Hexagram speak most directly to it.
What to pay attention to after the cast
Start with the Primary Hexagram and its main theme. Then look at the lower and upper trigrams and ask how those two forces relate to one another. If changing lines are present, pay special attention to their positions because they show where the strongest movement is taking place. Finally, compare the Primary Hexagram with the Relating Hexagram and notice what has changed between them.
The most useful reading usually comes from looking at the whole structure: the question, the six lines, the primary figure, the changing lines and the relating figure together. Use the interpretation to clarify the situation, then decide what the reading is asking you to notice, change, accept or approach differently.
